UniprotKB/SwissProt ID: Q9UBH6 (Q9UBH6)
Gene Name:
XPR1
Organism: Homo sapiens (Human)
Function: Inorganic ion transporter that mediates phosphate ion export across plasma membrane (PubMed:23791524, PubMed:25938945, PubMed:27080106, PubMed:31043717, PubMed:39169184, PubMed:39325866, PubMed:39747008, PubMed:39814721). Plays a major role in phosphate homeostasis, preventing intracellular phosphate accumulation and possible calcium phosphate precipitation, ultimately preserving calcium signaling (PubMed:27080106). Binds inositol hexakisphosphate (Ins6P) and similar inositol polyphosphates, such as 5-diphospho-inositol pentakisphosphate (5-InsP7), which are important intracellular signaling molecules involved in regulation of phosphate flux (PubMed:27080106, PubMed:39169184, PubMed:39325866)
